Compile time dependency injection in Java with Dagger2

This post is just for reference. Need to further look into how to use the compile time feature of Dagger2 in Spring/Spring boot. Spring sometimes relies on runtime dependency injection using reflection. Resource 1 (from Baeldung) has a easy to understand example of using Dagger2 to inject dependencies.
